Before you begin, ensure you have met the following requirements:

• Programming language is Python 3.8.1.

• All dependencies install from pip install -r requirements.txt.

• Telegram API wrapper is python-telegram-bot V11.1.0.

You have to create on following resources:

• Online store in Elasticpath.

• Online database in RedisLabs.

• Telegram bot via @BotFather

Declare default environment variables in .env file:

MOLTIN_CLIENT_ID - Elasticpath client ID.

MOLTIN_CLIENT_SECRET_TOKEN - Elasticpath client secret token.

DATABASE_PASSWORD - Redis database password.

DATABASE_HOST - Redis database host.

DATABASE_PORT - Redis database port.

TELEGRAM_TOKEN - your telegram bot token.

YANDEX_MAP_KEY - key for access Yandex map API.

PAYMENT_TOKEN - token for access your payment service.

PAYLOAD - your secret payload for transfer verification.

Before run it recommended to install virtual environment:

python3 -m venv env
source env/bin/activate

From your command line:

python pizza_bot.py

Usage example:

This bot was deployed to Heroku. You can find this bot in Telegram by username: @pizza_super_bot and try its work. For payment you can use test credit card:

1111 1111 1111 1026

The Facebook bot provides access to the pizza-shop.

This bot use the api of Elasticpath service (before this service was called Molton). For using the bot it has to create webhook, that is why this bot was created on Flask framework.

All CRUD methods worked by API documentation.elasticpath.

Before you begin, ensure you have met the following requirements:

• Programming language is Python 3.8.1.

• Framework Flask

• All dependencies install from pip install -r requirements.txt.

• Create a page on the facebook.

• Create an application it is connected with your page. The full details about creating and installing your application you can read on Facebook for developers.

You have to create on following resources:

• Online store in Elasticpath.

• Online database in RedisLabs.

Declare default environment variables in .env file:

MOLTIN_CLIENT_ID - Elasticpath client ID.

MOLTIN_CLIENT_SECRET_TOKEN - Elasticpath client secret token.

DATABASE_PASSWORD - Redis database password.

DATABASE_HOST - Redis database host.

DATABASE_PORT - Redis database port.

PAGE_ACCESS_TOKEN - your facebook page access token.

This is instruction for starting the bot on a local computer.

Before run it recommended to install virtual environment:

python3 -m venv env
source env/bin/activate

Because the facebook bot was based on the webhook and the facebook app need to connect to a server you need to emulate server on your local computer. You can use service Ngrok

After install from your command line:

python app.py
./ngrok http PORT

The PORT you can see when you start app.py. For example - Running on http://127.0.0.1:5000/, where 5000 is your local port.

After launch the server check your ngrok status:

Local addresses is highlighted red line, but facebook app accept only https protocol.

Usage example:

This bot was deployed on Heroku cloud platform. For online usage please go to facebook page Devman education, then go to messages and send /start.

You can copy, distribute and modify the software.
